[COLOR=465584]With the ATH-IM02 plugged into the headphone jack of my laptop and nothing playing, I hear a hiss sound. Like empty radio channel when u searching for stations, if u get what i mean. I have to turn the volume of the song higher than usual to drown out the sound. When starting up laptop, also got sounds.I dont get that the sound when its plugged into my iphone 5.

Unfortunately that's probably your laptop creating the noise and the IM02 picking it up because it's more sensitive than your full-size cans.
An external dac/amp is usually the easiest solution for this....
